Note: I am not promoting any site or service here. This is just a list taken from the internet. Never donate any amount to Bitcoin Accelerator on this forum. Because they might be using someone else's free service to accelerate your TX.

Not sure who (Mr.Spider703) this other guy is, but there's no need for accelerating transactions of any fee (that's been the case for a while now) ATM.- You can use 1 sat as TX fee and still gets confirmation in less than an hour.- Check how low the mempool (unconfirmed transactions) is nowadays.
